摘　　要：麻家梁矿区分布供电高压线路共11趟,高压供电铁塔共263个,压覆煤炭资源约3亿t。为了解放高压供电铁塔下的煤炭资源,麻家梁矿区建立了地表移动观测网,确定了岩层移动的地表预计参数。据此揭示了麻家梁矿区厚松散层条件下综放开采覆岩破坏的规律,为厚松散层工作面高压供电铁塔下采煤的影响评价提供重要依据,进而对高压供电铁塔下采煤制定综合保护措施。There are 11 high-voltage power supply lines and 263 high-voltage power supply towers in the Majialiang mining area,covering about 300 million tons of coal resources.In order to liberate the coal resources under the high-voltage power supply tower,the Majialiang mining area established a surface movement observation network and determined the estimated surface parameters of rock formations moving.Accordingly,the law of overburden failure of comprehensive mining under the condition of thick loose layer in Majialiang mining area was revealed,which provided an important basis for the impact evaluation of coal mining under the high-voltage power supply tower of the thick loose layer working face,and then formulated comprehensive protection measures for coal mining under the high-voltage power supply tower.
